Find the following values, using the equations, and then work the problems using a financial calculator to check your answers. Disregard rounding differences. (Hint: If you are using a financial calculator, you can enter the known values and then press the appropriate key to find the unknown variable. Then, without clearing the TVM register, you can "override" the variable that changes by simply entering a new value for it and then pressing the key for the unknown variable to obtain the second answer. This procedure can be used in parts b and d, and in many other situations, to see how changes in input variables affect the output variable.) Do not round intermediate calculations. Round your answers to the nearest cent.

You are considering an investment in a mutual fund with a 4% front-end load. The fund charges a back-end load of 5, 4, 3, 2, and 1 percent if the shares are redeemed within the first 5 years, respectively. The expense ratio of 0.5%. Alternatively, you can invest instead in a bank saving account paying 6% interest per year.

1. If you plan to invest for 3 years, what annual rate of return must the fund portfolio earn for you to be better off in the fund than in the bank saving account? Assume annual compounding of returns.

2. How does your answer change if you plan to invest for six years? Why does your answer change?

3. Now suppose that instead of a front-end load the fund assesses a 12b-1 fee of 0.75% per year. The back-end load will be 5, 4, 3, 2, and 1 percent if the shares are redeemed within the first 5 years, respectively. Then what annual rate of return must the fund portfolio earn for you to be better off in the fund than in the bank saving account if you plan to invest in 10 years?
